Computational fluid dynamics (CFD) simulation was carried out for an oscillatory flow in a 3-D realistic model of the human central airways, and the effect of airway geometry on the oscillatory flow structure was revealed. The computational model ...
This paper deals with an experimental study on the performance of a new type of heat transportation pipe utilizing self induced oscillatory flow. The pipe is heated at its bottom and cooled at its top. Experimental setup was composed of heating pa...
This paper deals with an experimental study of ice piece separation on a cooling surface. We used 1wt% NaOH-water solution as a heat storage material. Gas bubbles were generated on the cooling surface by supplying DC current. The generated gas bub...
